*strokes his 9800PRO, "its alright...shh" * No, I'm actually happy with my card at the moment, and thats rather old, so I'm sure the 6800GT can blow it out of the water and probably even into space
The stutter probably isn't the cards fault though, not if its running at 85-90FPS.
Nvidia always skimp on a few things though on there cards, for instance, effects are processed in 16bit or something, whereas ATI processes them at 32bit. Something like that.
That card holds the crown though, and will be the best for a while. ATI's version to beat that card missed it by a few FPS each time, so it can't be all bad
I've heard that even his are good, he tends to fill them with things that don't matter to the average gamer, for instance, loads of lights, and fans that don't necessarily cool anything down...
